Q: Fixing "warning: aggregate has a partly bracketed initializer"

[Charlie Zender]

Hi,

I have header files which instantiate 2-dimensional
arrays with const floats. When I compile the code below
with g++ -Wall, these initializations generate one of
the following warning messages for each line of data:
"warning: aggregate has a partly bracketed initializer"
What is the preferred method to initialize 2-dimensional
arrays? I am looking for a method which does not generate
warning messages when compiled with g++ -Wall.

const long nbr_LSM_pnt_typ(14);
const long nbr_mth_per_yr(12);
const float gai[nbr_LSM_pnt_typ+1][nbr_mth_per_yr]={
4.1,4.2,4.6,4.8,4.9,5.0,4.8,4.7,4.6,4.2,4.0,4.0,
0.0,0.0,0.0,0.6,1.2,2.0,2.6,1.7,1.0,0.5,0.2,0.0,
4.5,4.5,4.5,4.5,4.5,4.5,4.5,4.5,4.5,4.5,4.5,4.5,
...
0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0}; // end gai[]

Thanks,
Charlie

Put brace brackets around each 'row' of your 2-d array, e.g.:
{4.1,4.2,4.6,4.8,4.9,5.0,4.8,4.7,4.6,4.2,4.0,4.0},
{0.0,0.0,0.0,0.6,1.2,2.0,2.6,1.7,1.0,0.5,0.2,0.0},

and so on.

Tip: for readability, put a space after each comma - commas and dots can be
difficult to distinguish on some monitors.
